Background module not ground

De background of a created module for protostar template on position-8 is not the same as on the left site (position-7); There's no light-grey background and no rounded corners. How can I get it the same as on the rightsite ? Or do i have to re-install the protostar template and if so where can I download it?
I am working with Joomla 3.02.
